Multi-Resource Scheduling Signaling for Wireless Access Nodes
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current wireless communication systems operating at high frequencies, such as mmW-RAT, inefficiently use radio resources as they signal scheduling information for only one type of resource at a time, leading to suboptimal spectral efficiency due to differing data transmission configurations required for different types of radio resources.
Innovation Solution
A method and system for generating and transmitting scheduling messages that allow for data transmissions over multiple types of radio resources, enabling the use of optimal configurations for each resource type, thereby increasing overall throughput.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Loss of information
If scheduling information is signaled for only one type of resource at a time, then the signaling complexity is reduced, but the spectral efficiency deteriorates due to suboptimal resource utilization
Solution Approach 1:
The scheduling message is segmented into multiple scheduling information segments, where each segment corresponds to a specific type of radio resource (dedicated, shared, or unused dedicated resources of neighboring link). This segmentation allows the system to provide optimized scheduling information for each resource type separately, improving spectral efficiency while maintaining manageable signaling complexity through structured organization.
Solution Approach 2:
A single scheduling message is designed to serve multiple functions by incorporating multiple scheduling information segments that can schedule different types of radio resources. This multi-functional scheduling message eliminates the need for separate signaling for each resource type, thereby improving spectral efficiency without proportionally increasing signaling complexity.
2Productivity
If separate scheduling messages are generated for each resource type, then the spectral efficiency is improved through optimal configurations, but the signaling overhead increases
Solution Approach 1:
Multiple scheduling information segments for different resource types are merged into a single scheduling message. This consolidation allows the system to convey optimized scheduling information for dedicated resources, shared resources, and unused neighboring link resources simultaneously, improving throughput while avoiding the overhead of transmitting multiple separate messages.
3Quantity of substance
If a single scheduling message schedules multiple resource types, then the signaling overhead is reduced, but the adaptability to different resource characteristics deteriorates
Solution Approach 1:
Each scheduling information segment within the scheduling message is tailored to the specific characteristics of its corresponding resource type. Dedicated resource segments optimize for reliable data transmission, shared resource segments optimize for spectral efficiency, and unused neighboring link resource segments optimize for interference management. This local optimization within a unified message structure maintains adaptability while reducing signaling overhead.
